What does HRESULT 0x80EE003D (RTC_E_PROFILE_INVALID_SESSION_TYPE) mean?

RTC_E_PROFILE_INVALID_SESSION_TYPE

What the RTC value marks: RTC_E_PROFILE_INVALID_SESSION_TYPE

This result is useful only when preserved with its producing phase; in creating or enabling an XML profile that defines user identity, servers, transports, authentication, and supported session types, it denotes the profile contains an invalid session type value or combination.

The machine-readable identity of this result is 0x80EE003D in the RTC interface facility 0xEE; the result identity matters because RTC uses separate facilities for API conditions, SIP final responses, and PINT service statuses.

Before changing configuration, record the exact value, XML element, allowed enumeration, and related transport/role/session fields; the RTC codes surrounding this result are not equivalent because the field is present, so adding another copy will not fix semantic validation.

Protocol and object state

Evidence that separates the cause

Do not wait for a generic failure notification to log it; preserve the API call or event producing it together with the RTC object and transaction state visible at that moment.

• Code-specific proof: record the exact value, XML element, allowed enumeration, and related transport/role/session fields.
• Identity and target: redacted profile XML path/version.
• State at production: user URI and profile key hash.
• Timing and ordering: server role/address/transport.

A safe diagnostic sequence

1. Start from 0x80EE003D, then find the method/event pair that first exposed it.
2. To verify this, record the exact value, XML element, allowed enumeration, and related transport/role/session fields.
3. Keep the analysis at the right boundary: the field is present, so adding another copy will not fix semantic validation.
4. After you replace it with a documented value consistent with the rest of the profile and revalidate from source, repeat the smallest reproducer rather than restarting the entire application environment.

How to handle the result

Recovery should be narrow: replace it with a documented value consistent with the rest of the profile and revalidate from source; while handling this result, do not let a higher layer simultaneously recreate the same session, registration, listener, or profile.

Example: An automated profile feed emits an unsupported session type value and CreateProfile rejects the document.

Actions that do not address this condition

• Do not insert placeholder values solely to pass schema validation.
• Do not log passwords or provisioning secrets from profile XML.
